Static code integrated into operation procedures, such as within a vulnerability scanner, can spot new vulnerabilities in old code. Snyk Code is a close competitor for Veracode Static Analysis in its use for developers because of the detailed information that the testing results provide for programmers. Unlike Veracode, however, Snyk Code doesn’t support security testing for operations teams. A distinctive feature of this tool is that it isn’t just available as a continuous tester for CI/CD pipelines but it is also accessible as an on demand tester.
Static code analysis is typically done early in the software development process, often as part of the development itself. It can be used to identify defects and potential issues in the source code, such as syntax errors, logical errors, and potential performance and security issues, and help to improve the overall quality of the code. Additionally, static code analysis tools lack visibility into an application’s deployment environment. Unlike Dynamic Application Security Testing tools, which can be deployed in production or realistic testing environments, SAST tools never run the code. This makes them incapable of detecting misconfigurations and other issues not detectable within the application code. For example, some are not environment- or platform-agnostic; and some support a limited set of frameworks and languages.
Reviewing Source Code for SQL Injection
Now let’s explore how to integrate SAST tools into the DevSecOps pipeline. Difficult to ‘prove’ that an identified security issue is an actual vulnerability. Frequently can’t find configuration issues, since they are not represented in the code. For things that such tools can automatically find with high confidence, such as buffer overflows, SQL Injection Flaws, etc. they are great.

A point that needs to be addressed is why developers prefer to choose static code analysis tools over dynamic . A static analysis toolscans code for common known errors and vulnerabilities, such as memory leaks or buffer overflows. The principal advantage of static analysis is the fact that it can reveal errors that do not manifest themselves until a disaster occurs weeks, months or years after release.
Benefits of Static Code Analysis
A static code analysis tool will often produce false positive results where the tool reports a possible vulnerability that in fact is not. This often occurs because the tool cannot be sure of the integrity and security of data as it flows through the application from input to output. It supports several IDEs, custom code analysis rules, instant real-time feedback, CI/CD, multiple languages, vulnerabilities detector, Git hook, and more.
It is provided as a SaaS platform and it can scan code on demand, which means that it can be used as a vulnerability scanner by operations teams as well as providing continuous testing during code release. The tool offers security feedback in real-time and can cut mistakes made in new code by about 60 percent using an IDE scan. In addition, the developers are constantly learning as the tool continuously gives them just-in-time training to solve code bugs. Apart from supporting over 25 major programming languages and frameworks, this tool offers agile updates backed by their in-house security research team.
Examples of issues identified by static code analysis:
SonarQube is a comprehensive code quality platform that helps developers and DevOps teams proactively monitor source code quality and track their technical debt. Imagine that you could find bugs and security vulnerabilities and improve the code quality of your source code before uploading it to production. Static code analysis is used for a specific purpose in a specific phase of development. There are a few examples of usability static code analyzers, but they are less common than other types of static code analyzers. Performing useability testing manually usually makes the most sense.
- This tool competes with the self-hosted SonarQube because it can be installed on Windows, macOS, and Linux.
- This is critical in measuring how early in the software development life cycle the tools can be used; the earlier it can be used, the more effective it becomes.
- The current state of the art only allows such tools to automatically find a relatively small percentage of application security flaws.
- Embold is an example static analysis tool which claims to be an intelligent software analytics platform.
- Addressing issues earlier in the SDLC can reduce the cost of fixing bugs and other issues later in the process.
- For example, some are not environment- or platform-agnostic; and some support a limited set of frameworks and languages.
- Moreover, it serves to decrease technical debt, increase development productivity, bolster data security, and enhance visibility.
Nevertheless, static analysis is only a first step in a comprehensive software quality-control regime. After static analysis has been done, dynamic analysis is often performed in an effort to uncover subtle defects or vulnerabilities. In computer terminology, static means fixed, while dynamic means capable of action and/or change.
Over-reliance on the tool
Analysts frequently can’t compile code because they don’t have the right libraries, all the compilation instructions, all the code, etc. Taint Analysis attempts to identify variables that have been ‘tainted’ with user controllable input and traces them to possible vulnerable functions also known as a ‘sink’. If the tainted variable gets passed to a sink without first being sanitized it is flagged as https://www.globalcloudteam.com/ a vulnerability. Formal methods is the term applied to the analysis of software whose results are obtained purely through the use of rigorous mathematical methods. The mathematical techniques used include denotational semantics, axiomatic semantics, operational semantics, and abstract interpretation. Code metrics can be a powerful tool for helping to clean up and improve the quality of a code base.
Both static and dynamic code analysis techniques can detect software bugs during the development cycle. As compared to static analysis, dynamic analysis involves testing the application code during runtime execution. Often, static and dynamic code analysis combine to improve the effectiveness of the testing process. Simply put, static code analysis is the software testing technique used to analyze static application code for errors or flaws. Because it analyzes or tests applications without executing or running them. This means that application testing occurs without a runtime environment or during production.
The most popular tools for static security testing
Static Code Analysis is usually performed as part of a Code Review (also known as white-box testing) and is carried out at the Implementation phase of a Security Development Lifecycle . Static code analysis can be executed what is static code analyzer either manually or by using automation tools. However, the manual process of code review is difficult and time-consuming. First, it scans source code for defects like coding flaws, memory leaks, and data races.
Lintian– Checks Debian software packages for common inconsistencies and errors. Static code analysis is very powerful and flags issues in different categories . Applied to the AST shown above, the rule would then return false because there is only one argument to the function call requests.get with the name url. Only the timeout argument is passed to the requests.get function call, the function checkNode would return true. Let’s take the example of a rule that analyzes Python code and checks if the get method from the requests package uses an argument timeout. The Software Development Lifecycle outlines the stages that a development team passes through when creating, deploying, and maintaining software.
